additional information

The recommended combination of Dutch Formula 1, 2 and 3 during the 18 hour vegetative stage is the best guarantee for high quality results and strong, healthy plants with lush green leaves. Dutch Formula GROW creates the ultimate conditions for crop production during the next stage. You should stop the application of GROW between 21 and 30 days after your plants have entered the twelve hour flower phase.

By mixing the mineral components of Dutch Formula with water, you will get a rich and balanced nutrition for your plants. The Dutch Formula is suitable for all kinds of growing media. Comprehensive dosage information can be found on this page.
